More an FYI than an issue, I was able to make some changes to the 3 INSTALL files to allow Ubuntu 19.10 (I use Pop!_OS 19.10) and I was able to successfully flash my VIM3.
All I did in the files rk-flash-tool/INSTALL and toneboard-dfu-tool/INSTALL was literally change the 18 to a 19. In the root INSTALL file, I changed it so it installs lib32ncurses6 for Ubuntu 18.10, 19.04 and 19.10.
I'd be happy to do more testing and / or provide more information if you want to "verify" this version.
